Sipeccation of Letters Patent.

Patentedy April 2, 1907.

Application filed January 25, 1906. Serial No. 297,725.

To rtZi/ whom, it may concern: p

Be it known that I, JAMES H. Wns'roorr, a citizen of the United States, residing at Oneida, in the county of Madison and State of New York, have invented certain new and useful AImprovements in Compound Vises, of

which the followingis a specification, lreference being had therein to the accompanying.

drawings. U. My invention relates .to a compound 'benchvis'e; and I declare that the following is a full,

' in size and shape of different articles to be manufactured. It is intended for convenient use in machine-shops and the like, being readily adaptable for different conditions.

In brief, it comprises the fixed abutment portions and the separate sliding portions, so constructed and mounted that both may be brought to hold the work against the fixed portions, being-equally screwed up, or one may be screwed fully against the work and the other screwed to hold it by intervening blocks.

In the drawings, Figure i is a plan view ofA the device, one of the sliding blocks andthe top of the screw -journal being removed. Fig. 2 is an end view of one of the sliding blocks, and Fig. 3 of the end of the hase on which it slides, part broken away. Fig. 4 is a top view of the block, showing one form of. it, which is shown in end view in Fig'. 5. Fig. 6 is a side view.

The base portion is shown by A and has suitable means to secure it to the bench, and

on it are the abutmen'ts or fixed blocks A A,

arranged at an angle to each other and having the smoothed faces a and a. The base is extended in arms, one Opposite each block A and A. Each arm is slotted, as at a, to receive the guides c on the sliding blocks C, the blocks being held by screws inserted at the bottom through plates c. Only one but on one of the arms the cuts are extended into the angle between blocks A A, so that one block can be forced close to its corresponding abutment or head. The block is screw-.bored at c for the screw D, 'which is journaled in block d', having the cap d. The

turning of the screw moves the sliding blocks to and fro. The block has smoothed face ca. Either or both arms may have these grooves extended to the desired point.

It will be seen that in handling small articles one of the blocks can be crowded into the angle to hold the work against the opposite block or head, while the other may be used to hold the work by intermediate blocks Abetween the work an'd the sliding head. This gives one positive hold or grip on the work,

which is a distinct convenience and one ad' vantage of my im rovement over tlie con str uctions where llngblocks wereneeded against both sliding parts.

InIFigs. 4 and 5 I illustrate -a construction in which the sliding block is made up of parts.l

A'portion C is separate from main part C, the

line of separation being angular to the edges, so as to secure. a rm abutment, and it' may also have the dovetail joint cb. (Shown by dotted lines in Fig. 4.) The vertical cut between C and C" is such as to -include in the latter a threaded surface for screw I), and the 'guide c aids to hold block C in place. The block C may be secured by bolts or otherwise, as desired, andrbe given any suitable form. By use of such a block without part C the two sliding blocks can be brought to a much smaller field, as shown by dotted lines in Fig. 1. I indicate but a -single form of such built-up block, expressing therein the Yidea which may-be given a variety of forms.

So, also, various modifications of the device are within the range Ofmechanical skill and a'lso'within the scope of the invention, thoughnot shown or described herein.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is- 4 1. A` combined vise having fixed abutments and sliding abutments, one opposite IOC' to each fixed abutment adapted to be passed 1 into the iield in front of the other sliding abutment, one of the said sliding abutments such groove or slot in each arm may be used; [having its gripping portions made up of Darts 'und oppositeI lixod abntnionts, one of said interlocking and removable to reduce tllo dovotnilorl inlotlienmin face of said portions, substantially as d0-4 scribed.

2. In a combined Viso, slidinzgI abntments mont und havingy ai portion thereof in operative Contact with tbc block-actuating means. In testimony whereof I aflix my signatur@y in presence of twol witnesses. sliding nbutnionts boingrooinposito to pro- JAMES H.
